So I ordered an underworks binder at last. (I've been getting crappy amazon ones for awhile now :P) AND GOOD GRACIOUS IT IS A WHOLE NEW WORLD. It fits so nice on my back and omigosh my chest has never been flatter. Also, for you trans feminine lovelies here on the forum, underworks also does femme shape-wear. The whole site is just shape-wear and I LOVE IT. AAAH!
Here's a link if anyone's interested. It's split binary male and female, but it's still a pretty great site if your looking for quality stuff.
